__init__(self,
out)(Constructor)

Instantiate a line-oriented interpreter framework.

The optional argument 'completekey' is the readline name of a
completion key; it defaults to the Tab key. If completekey is not None
and the readline module is available, command completion is done
automatically. The optional arguments stdin and stdout specify alternate
input and output file objects; if not specified, sys.stdin and sys.stdout
are used.
